STOVE-BLOWER.

Application filed July 31, 1915.

To all whom it may concern:

Be it known that 1, FRANK Si-IADLEY, a citizen of the United States,residing at Hebron, in the county of Porter and State of Indiana, haveinvented certain new and useful Improvements in Stove-Blowers, of whichthe following is a specification.

The present invention relates to a fan blower attachment for cookstoves, and has for its object to provide a device of this characterwhich can be readily mounted upon an ordinary cook stove and embodiesnovel features of construction whereby a forced draft can beconveniently obtained at any time when such may be found desirable.

Further objects of the invention are to provide a fan blower attachmentof this character which is comparatively simple and inexpensive in itsconstruction, which can be easily operated, which can be moved .into anout of the way position when not in use, and which provides a simple andeffective means for obtaining a. forced draft at any time.

Vith these and other objects in view, the invention consists in certainnovel combina tions and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is afront elevation of a cook stove, showing the stove blower appliedthereto, the said blower being shown in inoperative position by solidlines, and in opative position by dotted lines. Fig. 2 is an enlargedlongitudinal sectional view through the stove blower, showing the mannerof attaching the air pipe to the stove. Fig. 3 is a transverse sectionalView through the stove blower, taken on the line 3-3 of Fig. 2, portionsbeing broken away.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

Specifically describing the present embod iment of the invention, thenumeral 1 designates an ordinary cook stove which is of the conventionalconstruction, having a fire box 2 at one end thereof and communicatingat its opposite end with the stove pipe 3.

The blower includes a cylindrical casing Specification of LettersPatent.

1 which is horizontally disposed and communicates at the bottom thereofwith an air chamber 5, said air chamber being tapered toward the bottomthereof, where it is connected to a downwardly extending air pipe 6.Extending axially through the cylindrical casing a is a fan shaft 7, oneend of which projects into a gear casing 8 arranged at the end of thefan casing 4. A. pinion 9 1s keyed upon or otherwise rigidly applied tothe end of the fan shaft 7 and meshes with a large gear wheel 10 mountedwithin.

the gear casing 8 and keyed upon a short shaft 11, This shaft 11 extendsbeyond the gear casmg 8 and is provided with a crank handle 12 which isused for the operation of the blower. In the present instance the crankcase 8 is shown as mounted eccentrically with respect to the fan casing4 and as projecting downwardly below the same.

The end of the fan casing 4L opposite to that upon which the gear casing8 is mounted is provided with a centrally disposed air inlet opening 13.The fan blades are formed of a pair of sheet metal plates 1d of a suitable size to rotate within the fan casing 4, said plates being appliedto the fan shaft 7 from opposite sides thereof and connected by means ofbolts 15 which clamp the plates rigidly in position upon the fan shaft.With this construction it will be obvious that the fan blades can berapidly rotated by turning the crank handle 12, and that this rotationof the fan blades will result in forcing a current of air through thedownwardly extending air pipe 6. The lower end of the air pipe 6 isprovided with an elbow 16 and a coupling 17 adapted to detachably engagea short pipe 18 embedded in the front of the fire box at an elevationslightly above that of the grate. When the coupling 17 is in engagementwith the short pipe 18 and the fan operated, a forced draft will beproduced in the cook stove.

The blower mechanism is mounted upon a swinging bracket 19 which may beconveniently formed of strap iron, one end thereof being rigidly securedto the air chamber 5, while the opposite end thereof may be suitablyconnected at 20 to the top of the stove 1 at a point toward the frontthereof. Such a construction admits of the blower being swung back intoan out of the way position when it is not in use. When it is desired toproduce a forced draft within the stove, the blower mechanism is swungforwardly into operative position and the coupling member 17 broughtinto engagement with the air pipe 18. A rotation of the handle 12 willthen produce the desired result.

Having thus described the invention, what I claim as'new and desire tosecure by Letters Patent, is

1. A stove blower, including a fan casing, a rotary fan mounted withinthe fan casing, gearing upon the casing for driving the fan, an air pipeprojecting downwardly from the fan casing, a coupling member at the endof the air pipe, a bracket mounted to swing in a horizontal plane andhaving the fan casing mounted upon the swinging end thereof, and a fixedpipe adapted to be engaged by the before mentioned coupling member atthe end of the air pipe when the casing is swung into operativeposition, the casing being adapted to be swung into an out of the wayposition when not in use.

2. A blower, including a cylindrical fan casing having an air inletopening in one end thereof, a gear casing applied to the opposite endthereof, a fan shaft extending through the fan casing and projectinginto the gear casing, a pinion applied to the fan shaft, a gear wheelmounted within the gear casing and meshing with the pinion, a crankshaft for turning the gear wheel, fan olades upon the fan shaft, an airchamber at the bottom of the fan casing, an air pipe projectingdownwardly from the air chamber, a coupling member at the end of the airpipe, a fixed pipe adapted to be detachably engaged by the couplingmember of the air pipe when the fan is in operative position, and asupporting bracket mounted to swing in a horizontal plane and having thefan casing mounted upon the swinging end thereof so 40 FRANK SHADLEY.
